<p>It's outposts like this that are keeping the venerable DQ brand in business. This place doesn't offer anything special, just a clean and welcoming fast-food establishment with sweet treats and "Sweet Deals", such as&mdash;a small sundae, a cheeseburger, fries and a drink for only five dollars. This location is less than a decade old, employees say, and it shows; Fairfax Station's DQ still looks brand-new. The dining room boasts a flat-screen television and a bunch of neat photos of Dairy Queens from the '50s and '60s.</p> <p>&nbsp;</p>
